I have a post-paid plan on Vodafone India on my SIM card (with BIS activated) but I havent used the phone/SIM since Jan 2011 (8 months) cos I left India for a few months to take a work position in Africa. I also had BIS de-activated from my Blackberry in Jan 2011 . Now I am going back to India for a one month holiday, so what do I need to do to re-activate BIS on my BB (model 8900), and what documents will I need?Thanks
